No paint, but 75 years of rust, = and conformation of string and agraffe to each other. After attending a = David Betts seminar on agraffes at the Arlington convention, I restrung = two of the worst notes, following David's procedure for cleaning and = reaming (tool available at Pianotek) the agraffe. What a difference! = Those 6 strings now render as smoothly as any strings on any piano I = have run into. I mean to do a couple more strings, leaving the agraffes = alone, and a couple more agraffes leaving the original strings in place, = to try to isolate the biggest contributor to the improvement, but = haven't gotten around to it. Regarding paint, I am doing some action work on a M&H BB for a dealer, = which he had restrung by someone else. There is a lot of gold paint on = the strings, looks like overspray from touching up the plate. I have = tuned this piano, and didn't notice any problems with string rendering. = Maybe the paint doesn't extend into the agraffe bearing surfaces, but my = bets are on rust, conformance, and burrs on the agraffe, not paint. Good luck selling the restringing job!

It has always been a nasty piano to = tune. Sounds like we have a good reason to restring. Yes? If the customer can afford it GO FOR IT !
